Description

Computer machine case rack with dust removal function

Technical Field

The utility model relates to a computer equipment technical field, concretely relates to computer machine case rack with dust removal function.

Background

The computer is an indispensable tool in modern society, provides powerful support and convenient service for modern office, and in school education, a computer course is an indispensable tool, so schools mostly have own computer rooms.

The computer room is used as a public area of a school, the phenomena of high use frequency, frequent replacement of users and poor environment in the computer room exist, computers in the computer room are required to be well protected as properties of the school, the external environment influence of the computers is mainly due to the blockage of heat dissipation holes caused by much dust in the computer room, the heat dissipation of the computers is influenced, although the school computer room has strict environmental sanitation requirements, however, because of the long-time use, the idle period such as cold, hot, and holiday, and the like, the problem of dust accumulation is very easy to cause, generally, computer cases in a computer room are mostly placed on the ground or a placing rack, the invasion of dust can not be blocked, and the condition of affecting heat dissipation exists, during dust removal operation, because most of the heat dissipation holes are arranged at the rear part of the case, the case needs to be taken out of the computer desk, certain danger exists, the case is easy to be damaged, and released components inside the case are loosened.

SUMMERY OF THE UTILITY MODEL

To the not enough of above-mentioned prior art, the utility model aims to solve the technical problem that: how to provide a computer case rack that has dust removal function that can remove dust independently, need not to move the machine case, simple structure, convenient operation.

In order to solve the technical problem, the utility model discloses a following technical scheme:

a computer case placing frame with a dust removal function comprises a horizontally arranged bottom plate, two side plates are oppositely arranged on the bottom plate, the top ends of the side plates are fixedly connected through a top plate, a back plate is arranged on one side of each side plate, a heat dissipation net is arranged between the back plate and the side plates, the rear plate is provided with a dust removing device which comprises a chute vertically arranged on the rear plate, a lead screw is rotatably arranged in the chute, one end of the lead screw is in transmission connection with a power input device, the screw rod is provided with a nut which is arranged in the chute in a sliding way, the nut is fixedly connected with a connecting rod which is horizontally arranged, one end of the connecting rod, which is not provided with the nut, is fixedly connected with a horizontally arranged cross bar which is vertical to the connecting rod, bristles are uniformly distributed at one end, far away from the connecting rod, of the cross rod, and a dust collection mechanism is further arranged on the bottom plate.

When in use, the case is put into the placing rack through one end without the back plate, so that the heat dissipation holes of the case are opposite to the back plate, in the daily use process, the heat generated by the self heat dissipation of the case can be dissipated to the outside through the heat dissipation net, thereby avoiding the formation of a relatively closed space by the placing frame, being beneficial to the self heat dissipation of the case, in addition, the environment around the case can be cleaned by opening the dust absorption mechanism, thereby avoiding dust from entering or blocking the heat dissipation holes, when several items need to be removed dust, the power input device is opened, the power input device enables the screw rod to rotate, the nut is in vertical motion along the sliding groove under the action of the screw rod and the sliding groove, the nut drives the connecting rod and the transverse rod to move up and down, the brush on the transverse rod cleans and brushes the heat dissipation holes in the case, and the generated dust is recycled through the dust collection mechanism. The utility model is simple in operation, convenient to use can clear away around the quick-witted case and the dust of louvre effectively, has reached the effect of protection computer, is favorable to prolonging its life, and in addition, application scope is wide, is fit for the not quick-witted case use of equidimension.

Preferably, the power input device comprises a micro driving motor, the micro driving motor is arranged on the top plate, and an output shaft of the micro driving motor is in coaxial transmission connection with the lead screw.

Therefore, the power output of the micro driving motor is stable, the required power is low, the lead screw can be driven to rotate stably, energy can be saved, and the micro driving motor is easy to control.

Preferably, the screw rod is arranged in the sliding groove through a bearing.

Therefore, the lead screw can rotate more stably and smoothly after being driven by the driving force, the friction force of the lead screw is reduced by the bearing, and a certain supporting effect can be achieved.

Preferably, the dust collection mechanism comprises dust collection holes uniformly formed in the bottom plate, the dust collection holes are connected with a micro air pump arranged on the bottom plate, and one end of the micro air pump is connected with a dust collection box.

Like this, miniature air pump action for the downthehole negative pressure that forms of dust absorption can inhale the dust, plays the significance at the in-process of routine maintenance and quick-witted case dust removal, and the dust absorption hole is less, makes the air current great, can provide sufficient suction, and the absorption of guarantee dust avoids the dust of cleaing away to absorb into computer case inside once more, reduces the probability that causes secondary pollution.

And as optimization, support legs are fixedly arranged below the bottom plate.

Thus, the bottom plate has a certain distance with the ground, and the invasion probability of dust on the ground is reduced.
